This standard bike rack has a simple and classic design. Simultaneous bike securing from both sides is possible. The D bollard bike rack is available in our signature colors black, blue, green, yellow, and charcoal. OD sizes of 1 7/8” and 2 3/8” are selectable. The outside diameter of the “D” shape for the 2 3/8” option amounts to 1 7/8” inches. In general, this is a rather light bike rack in comparison with our assortment. This bike rack can be attached with either surface or in ground mounting. Fabricated with our high-quality tubing and coated with an extremely durable powder coat finish, this product is built to last.
